Overview
Brief Summary
The purpose of this clinical study is to evaluate the safety and immunogenicity of a 3-dose schedule (2-dose primary series followed by a toddler dose) of pneumococcal conjugate vaccine (PCV) as one of the currently recommended schedules by the World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) on Immunizations and practiced in many countries.
The primary hypotheses are that V114 is non-inferior to Prevenar 13™ for the 13 shared serotypes based on response rates and on anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobulin G (IgG) geometric mean concentrations (GMCs) at 30 days following Dose 3; that V114 is superior to Prevenar 13™ for the 2 serotypes unique to V114 based on the response rates and on anti-PnPs serotype-specific IgG GMCs at 30 days following Dose 3; and that Vaxelis™ administered concomitantly with V114 is non-inferior to Vaxelis™ administered concomitantly with Prevenar 13™ at 30 days following Dose 3 for each antigen included in Vaxelis™.

Outcomes
Primary Outcomes
Percentage of Participants With a Solicited Injection-site Adverse Event
Time Frame: Day 1 to Day 14 after each vaccination
An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Solicited injection-site AEs included injection-site erythema (redness), injection-site induration (hard lump), injection-site pain (tenderness), and injection-site swelling.
Percentage of Participants With a Vaccine-related Serious Adverse Event
Time Frame: Up to approximately 6 months after Dose 3 (up to approximately 16 months)
A serious adverse event (SAE) is an AE that results in death, is life-threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment. SAEs that were reported by the investigator to be at least possibly related to the study vaccination were summarized.
Percentage of Participants Meeting Serotype-specific Immunoglobulin G (IgG) Threshold Value of ≥0.35 μg/mL 30 Days After Dose 3
Time Frame: 30 days after Dose 3
The geometric mean concentration (GMC) of IgG serotype-specific antibodies to the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) included in V114 and Prevenar 13™ and 2 serotypes (22F and 33F) unique to V114 were quantitated from participants' sera by a multiplex electrochemiluminescence (ECL) assay. Immunoglobulin G for the 15 serotypes contained in V114 vaccine was determined using a pneumococcal electrochemiluminescence (PnECL) assay.
Percentage of Participants With a Solicited Systemic Adverse Event
Time Frame: Day 1 to Day 14 after each vaccination
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Solicited systemic AEs included decreased appetite, irritability, somnolence (drowsiness), and urticaria (hives or welts).
Geometric Mean Concentration (GMC) of Serotype-specific Immunoglobulin G (IgG) 30 Days After Dose 3
Time Frame: 30 days after Dose 3
